Usage

From source file:pushandroid.POST2GCM.java

    try {//from  w ww. ja  v a  2 s .  co  m

        // 1. URL
        URL url = new URL(URL);

        // 2. Open connection
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();

        // 3. Specify POST method
        conn.setRequestMethod("POST");

        // 4. Set the headers
        conn.setRequestProperty("Content-Type", "application/json");
        conn.setRequestProperty("Authorization", "key=" + apiKey);

        conn.setDoOutput(true);

        // 5. Add JSON data into POST request body
        //`5.1 Use Jackson object mapper to convert Contnet object into JSON
        ObjectMapper mapper = new ObjectMapper();

        // 5.2 Get connection output stream
        DataOutputStream wr = new DataOutputStream(conn.getOutputStream());

        // 5.3 Copy Content "JSON" into
        mapper.writeValue(wr, content);

        // 5.4 Send the request
        wr.flush();

        // 5.5 close
        wr.close();

        // 6. Get the response
        int responseCode = conn.getResponseCode();
        System.out.println("\nSending 'POST' request to URL : " + url);
        System.out.println("Response Code : " + responseCode);
